Abstract

A magnetic head (20) of a magnetic head device has a head guide (21) which has a groove (23) in its side surface. A support table (33) has a recess (33a) in which the lower portion of the head guide is fitted. Screws (41, 42) are screwed upward from the bottom of the support table and extend into the recess. The head guide is supported on the screws. An elastic plate (31) which has central and radially extending perforations (31a, 31b) at its center portion is mounted on the upper surface of the support table. A portion of the elastic member which defines the central perforation (31a) is fitted in the groove of the head guide. The head guide is then biased toward the screws. When the screws are turned, the level and azimuth of the magnetic head can be adjusted. A pressure pad (50) is also adjusted by other screws (64) to be set at a selected position relative to the magnetic head and at a selected tilt angle with respect to the magnetic head.
